I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

Christopher · Apr 2026 Trustpilot

I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

What the health check covers

Four core areas reviewed from your monitoring data.

Generation performance analysis

12+ months of actual generation versus expected output for your system size and location. Underperforming panels, inverter derating, and seasonal anomalies identified.

Battery health review

Charge and discharge patterns, depth of discharge, BMS events, estimated capacity versus rated capacity, and whether the battery is cycling correctly.

Settings and configuration audit

Export limits, CT clamp direction, charge schedules, system mode, tariff alignment, and firmware version. The most common sources of silent performance loss.

Monitoring verification

Confirm monitoring is live and capturing all data correctly. Check SEG export registration status, and flag any data gaps that could affect payments or warranty claims.

What we check during a solar health check

A comprehensive physical and performance audit across all major systems.

Panel condition

Visual inspection for hotspots, microcracks, soiling buildup, bird damage, and edge delamination that can degrade efficiency or void warranty.

Inverter performance analysis

Measured efficiency against manufacturer specification. Derating analysis, thermal throttling patterns, and firmware version validation.

Battery health assessment

Cell voltage balance, capacity degradation over cycles, charge/discharge curve analysis, BMS event logs, and estimated remaining usable capacity.

DC string voltage testing

Comparison between panel strings and baseline. Identifies failing panels, wiring losses, and voltage imbalances that reduce generation.

AC output measurement

Power quality analysis, frequency stability, and reactive power. Identifies issues that could affect grid export registration or tripping.

Earthing and bonding verification

Continuity testing and resistance checks across all earth points. Critical for safety and compliance with BS7909 and BS7671.

Isolator and switchgear condition

Physical inspection for corrosion, mechanical wear, and proper installation. Verification that manual isolators operate smoothly and isolate completely.

Wiring and connector inspection

Check for MC4 degradation, rodent damage, UV damage to cable jackets, and any loose or corroded connections that increase resistance and fire risk.

Monitoring system accuracy validation

Verify CT clamps are correctly installed and directioned. Confirm monitoring data aligns with actual generation. Identify gaps or sensor failures.

Roof fixings and mounting system

Visual check for loose bolts, corrosion on rails, and structural movement. Ensures panels remain secure in high winds and can't slide or shift.

Why annual health checks matter

Solar systems naturally degrade at a rate of 0.5–0.8% per year under normal conditions. This is expected and typically not a concern. However, undetected faults — failed panels, inverter drift, battery imbalance, wiring issues — can accelerate this degradation significantly. A system losing 10% output silently over two years will have generated thousands of pounds less than it should have, whether through lost generation, missed export payments, or prevented battery charging when you need it most.

Annual health checks catch these failures early, before they compound. Many solar warranties explicitly require evidence of regular maintenance and professional inspection. If you need to claim under warranty later, a gap in documented health checks can invalidate your claim. Battery systems especially benefit from annual checks: cell balancing, firmware updates, capacity testing, and BMS event analysis reveal issues long before the battery becomes unusable.

Early detection of panel faults is particularly valuable — a single failing cell can cause cascading damage to the entire string if left unchecked. Our physical panel inspections identify hotspots, microcracks, and soiling buildup that reduce efficiency. Regular audits also ensure your system remains compliant with safety standards (BS7909, BS7671) and that export registration hasn't lapsed. The cost of an annual health check (£145) typically pays for itself within days if any configuration issues are found and corrected. Proactive maintenance prevents silent output losses and catches system underperformance before it costs money.

Health check vs remote diagnostic

Remote diagnostic (£75)

Best for: Something is clearly wrong

▸Active fault codes and errors

▸Specific issue diagnosis

▸Rapid troubleshooting (30–60 mins)

▸Configuration error identification

▸Remote settings correction where safe

Perfect for urgent faults that need quick diagnosis and possible remote fix.

Health check (£145)

Best for: Proactive maintenance

✓Comprehensive physical inspection

✓Baseline performance benchmarking

✓12+ months of data reviewed

✓Hidden issues identified early

✓Warranty compliance documentation

Full system audit — catches silent degradation and configuration drift before they cost money.

Not sure which to book? Use a remote diagnostic if you have an immediate fault. Choose a health check if your system seems fine but you haven't had it checked in over 12 months, or if you want peace of mind before relying on generation for financial decisions. See our remote diagnostic service for more details.

How it works

Share monitoring access

Grant temporary read-only access to your monitoring account — GivEnergy, SolarEdge, Sunsynk, Growatt, Solis, or whichever platform your system uses. Takes about 2 minutes.

Remote audit (typically 2 hours)

We review 12+ months of generation data, battery performance history, system settings, and event logs. Any settings corrections that are safe to make remotely are applied during this step.

Written report delivered within 24 hours

PDF report covering all four areas with a priority action list. Pass/flag status on generation, battery, settings, and monitoring. Clear recommendations with estimated cost where relevant.

Optional follow-up call (no extra charge)

If you want to talk through the findings or aren't sure how to act on a recommendation, a follow-up call is included. No time pressure.

FAQ

Frequently asked questions

What's the difference between a health check and a diagnostic?

A health check benchmarks how your system is performing and configured right now — generation, battery, export, settings. A remote diagnostic is fault-focused: it finds what's broken. Book a health check if your system seems to be running but you want to verify it's working correctly. Book a diagnostic if something is clearly wrong — no generation, fault codes, battery not charging.

Do I need monitoring access to book?

Yes. We review generation history, battery data, and settings via your monitoring account — we can't audit your system without it. If you've lost access or the account is registered to the original installer, see our monitoring account transfer service first.

My system is under 2 years old — is this worth it?

Yes. New systems routinely have misconfigured settings — export limits set to zero, CT clamps installed backwards, charge schedules not aligned to the tariff. These cost money silently from day one. A health check typically pays for itself within weeks if any of these are found.

What happens if problems are found?

Findings are listed in priority order in the report. Settings issues we correct during the session where safe to do so. Hardware faults that need on-site attention are clearly flagged with recommended next steps. You're not committed to any further work — but a fixed-price quote is available if you want it.

How often should I book a health check?

Annually is ideal for most systems — particularly battery systems, which benefit from firmware updates and cell balancing. If your system is over 5 years old, two years without a check means accumulated drift that may be silently costing you. New systems (under 2 years) should have at least one health check to catch any commissioning errors. More frequent checks are worthwhile if you're relying on the system for financial projections (export income, battery cycling schedules, etc.).

What if a health check finds a major fault?

The report will flag it clearly with a severity level and recommended next step. For hardware faults (failed panels, inverter issues, battery damage), we provide a fixed-price quote for on-site repair or replacement before any commitment. For safety issues, we flag them immediately and mark them as priority. You're in control of what happens next — the report is yours to act on in your own time.

Can you check any solar brand?

Yes — we support all 19 major inverter brands, including SolarEdge, GivEnergy, Sunsynk, Growatt, Solis, Victron, Tesla, LG, Hyundai, and more. We also work with any panel manufacturer and battery type. If your system uses an unusual or very new brand, ask first — but we're confident we can audit it. The health check is fully brand-agnostic.
